The lock is the pin or French lock, which the Frenchforceps carry at the present time. In this instrument, too, thepelvic curve is inadequate, but the forceps has certain advan-. 1 rig. 514.âA, Levrets forcepswith a pelvic curve ; 15, Smellies for-ceps with a pelvic curve. 1 Levrel presented his forceps t tin- Academ) i Hfirsl published ;i < 1ti⢠.n i his in 1751, though he hadt n \ eai s before. rgeryi\ ente 1747.

It was not long before the disadvantage of the inade-quate pelvic curve was appreciated, and soon after the time ofSmellie and Levret this feature was improved, and a forceps witha better constructed pelvic curve came into use. It may benoticed that the handles of both the Levret and the Smellie for-ceps are rather difficult to grasp, if one desires to make a strongtraction upon them. This disadvantage was overcome by Busch,a German, who was the first to add the cross-pieces or shouldersto the handles, which enable the operator to take a firm andconvenient grip of the instrument.
